The first 'heretic' to be condemned to death at the end of IV century, Priscillian, sometime bishop of Avila, has generated much scholarly interest in early Christian studies since the rediscovery of his works in the nineteenth century. Early scholarly attention focussed on the question of Priscillian's heterodoxy. Was he really an orthodox thinker victimised by ecclesiastical politics or were the accusations of heresy fully grounded in his teachings? Recent scholarship has moved away from rigid categorisation of the individual and focussed on the social-political movement of Priscillianism, with a tendency to neglect the literary corpus. Marco Conti draws attention back to the writings and the theological reflections there contained. Published for the first time in one volume with facing page translation and systematic commentaries, The Complete Works provide invaluable material for better understanding the complex nature of this fascinating figure and the movement he inspired, a crucial example of early opposition to Ecclesiastical power. With an extensive introduction providing biographical and textual background information.
